Call BT on 0800 783 1401 and give 30 days' notice, or start with your new provider and it handles the switch. Inside a minimum term BT charges every remaining month plus VAT.
Mind My Money works through leaving BT with you and reads your BT account afterwards to see that it has ended.
This is for anyone leaving BT Broadband. The call itself is quick, and what costs money is the timing and the equipment. Everything is from BT's own help pages as they read on 19 September 2026.
It is on the home page of My BT online or in the My BT app. BT's minimum terms are usually 12, 18 or 24 months, and leaving inside one costs “the remaining amount you would have paid up to the end of your minimum period.” BT spells out the sum: “We take your monthly price, multiply it by the number of months left on each service contract, and add VAT.” Unlike some providers, BT describes no discount on that.
So with a few months left, the whole of those months is what you would pay, and waiting for the end date may be the cheapest way out.
If you are moving to a new provider, you start with them, and in BT's words “they will be responsible for handling your switch.” The notice period when you switch this way is 14 days rather than 30.
Call BT on 0800 783 1401 (Monday to Friday 8am to 9pm, Saturday 8am to 8pm, Sunday 9am to 6pm). There is no online cancellation. BT's leaving page shows your personalised offers before it gives the number, and you do not have to take one.
You need to give 30 days' notice, and the service stops 30 days after you cancel. If you want it to stop sooner, BT charges for the remaining days of the 30.
BT emails you a QR code and a printable label, and you take the equipment to a Royal Mail Customer Service Point, a Post Office or a Royal Mail parcel locker. BT's own stores only take mobile phones back.
You have 60 days from the date you stopped using it. After that BT charges for anything not returned, from £50 for a Complete Wi-Fi disc to £65 for a Smart Hub, £85 for a Smart Hub 3 and £140 for a TV Box Pro. Keep the Royal Mail receipt with its tracking barcode until the return shows on your account.
BT's examples show the final bill arriving within 10 days of the stop date. Check it for the notice period, any early termination charge and any equipment charge, and check your bank statement afterwards that the monthly payment has stopped.
If your address ends @btinternet.com, @btopenworld.com or @talk21.com, it comes with the broadband, and BT asks what to do with it as you cancel. You can close it, keep it on free Basic email, pay £7.50 a month for Premium, or link it to a friend or family member's BT Broadband for nothing. “If you don't make a choice yourself, we'll transfer you to Basic email.”
Basic is free and it is also where the mailbox gets stuck: “Access via www.bt.com only. You can't use this email with an email client or on your device.” No mail client means no bulk download, and BT's pages describe no export tool, so if you want a copy of years of email, take it while the broadband is still running.
Two clocks then start. If you close the email instead, you have 60 days to change your mind and upgrade to Premium; after that “all of the email addresses linked to your BT ID will be deleted” and “all of your personal data will be deleted and cannot be recovered”. And if you keep Basic, you have to use it: an account not logged into for 150 days is deleted, and reusing the address afterwards gets the address back but not the mail.
There is also an ordering trap worth knowing before the call, because it is the only part of this you cannot fix later. BT says “If you're leaving BT Broadband and want to get Basic email, you need to order it when cancelling your broadband. You can't make a direct switch later.” Decide it in the same conversation as the cancellation.
